HTTP Status 401 when trying to access dinamically generated URLs

﻿I'm using the Waffle Spring filter in a project based in the Ozone framework (GOTS software). I can access jsp pages not having a ? in the URL but I get﻿ ﻿﻿the 401 - This request requires HTTP authentication when the URL
has a ? mark (dinamicaly generated URL) like for example: ﻿

/owf/prefs/dashboard?_=1300248593791&version=3.3.0-GA-v1

I can see all my roles and my user principal name in the index.jsp I have inside the owf folder. In the Tomcat log I see that I'm successfully authenticated. My sewcurity context is

exactly like the example for the Spring filter. Is this a bug inside Waffle or is a problem inside the Ozone framework?

This last 401 doesn't come from Waffle (or you would have Authorization headers in the response). The only thing I am noticing is that it's an XMLHttpRequest, meaning that its an Ajax call from Javascript or something like that. Something else is saying
401 Access Denied, track that down.
